When engaged in anal sex(over a table or a bench top)and the man is about to ejaculate, he quickly punches her in the back of the head(to knock her out) and withdraws his penis ejaculating all over her chest when she is unconscious. Then he grabs one shoulder and the opposite leg and slides her across the table or bench(While she is still unconscious). With the assistance of the semen all over her chest she should be able to slide off the table with a decent throw.
